CULTIVATOR-SHIELD.

Specification of Letters Patent.

Patented Nov. 12, 1918.

Application filed August 30, 1918. Serial No. 252,048.

and JOHN C. S'roncK, citizens of the United- States of America, residing in the towns of Cottage Grove and Blooming Grove, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Cultivator-Shields, of which the following is a specification.

This invention relates to certain new and useful improvements in cultivator shields of that type which are intended to be attached to cultivators of the wheeled straddle-row type.

The primary object of the present invention is to provide a shield for cultivators of such a construction that lumps of soil are thrown between the planted rows, provision being made to move fine dirt up against the plants. 7 1

A further object of the invention is the provision of an adjustable mounting means for a cultivator shield, by means of which the shield may be regulated so as to be most effective in, various kinds of earth according to the lumpy or finer nature of the latter, I

A still further object of the invention is to provide an adjustable mounting means for a cultivator shield whereby the forward 5 end of the shield may be directed away from or nearer to a planted row to thereby attain best results according to various conditions met in cultivating.

\Vith the above general objects in view and others that will become apparent as the nature of the invention is better understood, the same consists in the novel combination, form and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed. 7

In the accompanying drawings forming part of this application, wherein like characters of reference refer to corresponding parts throughout the several views,

Figure 1 is a rear end elevation of a por tion of a cultivator with the present invention attached thereto;

Fig. 2 is a vertical sectional view taken substantially on line 11-11 of Fig. 1;

Fig. 3 is a perspective view, slightly enlarged, of the shield detached from the cultivator;

Fig. 4: is a longitudinal sectional view taken through the adjusting link and the adjacent portion of the shield substantially upon line IV--1V of Fig. 5; and

Fig. 5 is a side elevation of the adjusting link shown connected to a fragment of the shield.

Referring more in detail to the several views, the present invention contemplates the provision of a shield in the form of a plate 5 which is rounded as at 6 at its lower front corner and curved outwardly as at 7 along its upper longitudinal edge, the plate 5.being curved inwardly as at 8 along its lower longitudinal edge. A bar 9 is pivotally connected intermediate its'ends as at 10 to the central portion of the plate 5 and has a curved bar or strap 11 pivotally connected to the forward free end thereof as at 12. The bar 11 is provided with a number of perforations 18 to receive a set-screw 14 when positioned within one of the blocks 15 which are attached to the cultivator bars 16. This construction enables the cultivator shield to be adjusted forwardly or rearwardly to a correct position beside the shovels or cultivator blades 17.

The bar 9 has bolts 18 extended through theopposite ends thereof and these bolts also extend through arcuate oppositelyv disposed slots 19 provided in the shield '5, suitable winged nuts 20 being provided on the bolts 18 to firmly hold the-bar 9 and shield 5 against relative movement. It is obvious that by loosening the nuts 20. the shield 5 may be swung in a vertical plane about the pivot 10 relative to the bar 9 to thereby set the shield 5 at a proper position relative to the ground being cultivated.

Pivot-ally connected as at 21 to the shield 5 at a point substantially directly above the rear slot 19 is an adjustable link comprising sections 22 and 23 of channel form and slidable one within the other, as clearly shown in Fig. 5, the section 23 having a hook 2-1 pivotally attached to the free end thereof as at 25 to be engaged over the cultivator bar 17, as clearly shown in Fig. 1. The hook 24 has substantially parallel sides 26 and 27 which snugly engage opposite sides of the bar 17 so as to prevent any material lateral movement of the hook 24 relative to said bar 17. The link section 22 is provided with a longitudinal elongated slot 28 in the web thereof and a bolt 29 which extends through this slot and the inner end of the link section 23 has a'winged nut 30 screwed thereon to retain the sections 22 and 23 against relative displacement. It will be readily seen that by loosening the nut 30, the section 22 may be slidably moved relative to the section 23' to thereby swing the rearend of the shield 5 upon the hinge 12 to thereby move the forward end of the shield 5 toward or away from the planted row as desired.

The upper curved edge 7 of the shield prevents the earth from falling on the plants and throws said earth ontoythe shovels 17 between the rows, while the curved lower edge 8 of the shield will throw lumps of earth or the like between the rows. The, lower curve 8 will also serve to lift up the leaves of the plants and to shove the finer earth up against the plants. 1

In the use of the invention as herein illustrated, the shields are provided between the shovels 17 in spaced relation with their upper edges 7 directed away from each other 7 and their lower edges 8 directed toward each;

in the details of construction may be made without departlng from the spirit and scope of the invention as claimed.

What/We claim as new is l. A cultivator shield comprisinga plate,

a curved attaching strap pivotally connected adjacent the vforward end of said 'pla'te'to allow horizontal swinging of the latter, and adjustable means to connect the rear end of said plate to a cultivator bar whereby the forward end of said plate may be swung toward and away from a planted row horizontally.

2. A cultivator shield comprising an elongated plate, a-bar pivoted centrally to said plate intermediate the ends of the bar whereby the plate may be vertically swung relative to said bar, said plate being provided with oppositely disposed arcuate slot-s adjacent the opposite ends thereof, bolts extending through the adjacent ends of said bar and the adjacent slots and provided with nuts to maintain the plate and bar against relative movement, and means connected to said bar to attach said plate to a cultivator.

3. A cultivator shield comprising a plate, a bar pivotally connected to said plate whereby the plate maybe vertically swung relative to said bar, means to maintain said plate and bar against relative movement, an attaching bar pivotally connected to the firstnamed bar whereby'the plate may be horizontally swung relative to the attaching bar, and adjustable means connected to the plate and adapted for connection to a cultivator bar whereby the forward end of said plate may be moved toward and away from a planted row.

In, testimony whereof we aflix our signatures;
